Try running the sage_getdoc function a few times in a row with the same
input on 4.7 and 5.0 (or just using the question mark) and you should see
the difference. You really need to do it a few times in a row, though. The
first time may be slow because it is reading from disk (a "warm cache"
from starting up sage is not enough to prevent this) but it should not
remain slow.
